Description

CROSS REFERENCE TO RELATED APPLICATION

This application is a continuation application of U.S. Ser. No. 15/329,538, filed on Jan. 26, 2017, which is application is a US national phase application based upon an International Application No. PCT/CN2016/077013, filed on Mar. 22, 2016, which claims priority to Chinese Application No. 201510221196.1, filed Apr. 30, 2015. The entire disclosures of each of the above applications are incorporated herein by reference.

BACKGROUND OF THE DISCLOSURE 1. Field of the Disclosure

The present disclosure relates to the field of mobile communication technology, and more particularly, to a method of accessing to networks and a mobile communication terminal.

2. Description of the Related Art

Public land mobile network (PLMN) is a network built and operated by the government or operators approved by the government for the purpose of providing land-bound mobile communication services for the public. The network is usually connected to public switched telephone network (PSTN), forming a communication network that covers a whole region or country.

A network identity of the PLMN is usually just a string of numbers. For example, the network identity of PLMN of China Mobile is 46000, and the network identity of PLMN of China Unicorn is 46001. Through the mobile networks provided by each operator, users can enjoy rapid and convenient communication. The number of users carrying communication terminals has been on the rise as people's living standard elevates. When a user inserts a new user identification card into a mobile communication terminal for the first time, the mobile communication terminal (e.g. a cell phone) must search a network to acquire the network identity of the PLMN. However, when the user inserts the new user identification card into the mobile communication terminal for the first time, it usually takes the terminal a long time (sometimes even as long as ten to twenty minutes) to search the network. And, only when the terminal successfully found the network can it connect to the PLMN of the current location. It significantly influences users' communication experience.

SUMMARY

The embodiment of the present disclosure provides a method and mobile communication terminal for accessing to a network and reducing the time needed to connect to a PLMN, thus greatly improves users' communication experience.

The present disclosure proposes a method for accessing to a network. The method includes follows.

A network standard supported by the mobile communication terminal is determined.

A network identity of a public land mobile networks (PLMN) in compliance with the determined network standard supported by the mobile communication terminal is added to an equivalent public land mobile network (EPLMN) list.

A communication connection between the mobile communication terminal and a matching PLMN is established upon a condition that the matching PLMN is found to match the network identity in the EPLMN list.

The present disclosure also proposes a mobile communication terminal. The mobile communication terminal includes a standard determining unit, an adding unit, and an accessing unit.

The standard determining unit is configured to determine a network standard supported by the mobile communication terminal.

The adding unit is configured to add a network identity of a public land mobile networks (PLMN) in compliance with the determined network standard supported by the mobile communication terminal to an equivalent public land mobile network (EPLMN) list.

The accessing unit is configured to achieve a communication connection between the mobile communication terminal and a matching PLMN upon a condition that the matching PLMN is found to match the network identity in the EPLMN list.

The embodiment of the present disclosure determines the standard supported by the mobile communication terminal, and adds the network identity of the determined standard PLMN supported by the mobile communication terminal into the EPLMN list. When a PLMN is found to match a network identity in the EPLMN list, a communication connection between the mobile communication terminal and the matching PLMN is established. The embodiment of the present disclosure adds the network identity of the determined standard PLMN supported by the mobile communication terminal into the EPLMN list. The EPLMN list stores network identities of PLMNs that are regarded as equivalent to a certain extent by the mobile communication terminal. Therefore, when the mobile communication terminal connects to a network based on the EPLMN list, which has stored network identities of standard PLMNs supported by the mobile communication terminal, it searches networks based on the current location when it is inserted with a user identification card for the first time. Thus it significantly heightens the chance of finding a PLMN whose network identity matches a network identity that is already stored in the EPLMN list during the process of network searching, as well as the possibility of the mobile communication terminal accessing to a network at the current location. It is instrumental in minimizing the waiting time when users are communicating (ideally, it only takes a few seconds for the mobile communication terminal to complete network connection), and thus is instrumental in greatly improving users' communication experience.

However, it is understandable by persons skilled in the art that the application can also be implemented in other embodiments not providing such specific details. In other cases, details of a well-known apparatus, circuit and method are omitted to avoid hindering the description of the application by unnecessary details.

The embodiment of the present disclosure proposes a method and mobile communication terminal for accessing to a network to reduce the time needed for the mobile communication terminal to connect to a PLMN, thus greatly improves users' communication experience.

Please refer to FIG. 1. FIG. 1 is a flow chart of the method for accessing to a network according to an embodiment of the present disclosure. It can be applied to mobile communication terminals such as smart phones (e.g. android phones, iOS phones, and so on). The method for accessing to a network includes following blocks:

S101: Network standards supported by the mobile communication terminal are determined.

In the embodiment of the present disclosure, network standards refer to the types of the networks. Types of network standards commonly seen in China are code division multiple access (CDMA), with mobile phones using CDMA 1× at frequency band 800 MHz; global system for mobile communication (GSM), with mobile phones using frequency bands 900/1800/1900 MHZ; GSM 1× dual-mode (i.e. wideband CDMA, WCDMA) in the recent years, taking frequency bands 900/1800 HMZ; 3G mobile communication technology, taking frequency bands 900/1800/1900/2100 HMZ; and 4G technology, taking frequency bands 1920-2170 MHZ.

In the embodiment of the present disclosure, the network standards that can be supported by each mobile communication terminal are limited and definite. That is, after a mobile communication terminal is produced, the network standards supported by the mobile communication terminal are determined.

S102: Network identities of public land mobile networks (PLMN) in compliance with the determined network standards supported by the mobile communication terminal are added to an equivalent public land mobile network (EPLMN) list.

In the embodiment of the present disclosure, Public Land Mobile Network (PLMN) is a network built and operated by the government or operators approved by the government for the purpose of providing land-bound mobile communication services to the public. The network is usually connected to PSTN, forming a communication network that covers a whole region or country. For example, the network identity of PLMN of China Mobile is 46000, and the network identity of China Unicom is 46001. PLMN is a wireless communication system, inclined to be accessed by land-bound users riding on transportation tools or moving on foot. Such a system can be independent, but it is usually connected to a landline telephone system, such as PSTN. However, there are also more and more mobile and portable Internet users. An ideal PLMN system provides services to mobile and portable users equivalent to that provides to landline users. It can be especially challenging in areas with complicated terrains, because it is difficult to find and maintain a base station. There are also many obstacles in an urban environment, such as noises and interfering radiation that can be evoked by buildings and radio frequencies.

In the embodiment of the present disclosure, an equivalent public land mobile network (EPLMN) is a PLMN that has the same status and level of priority as the PLMN currently chosen by the user's terminal. The EPLMN mainly solves problems related to user retention and roaming strategy in shared networks and original networks. Operators can deploy equivalent PLMNs so to realize sharing of communication network resources. From a business perspective, the practice realizes sharing of communication network resources among different PLMNs defined by the same operator or PLMNs of different operators.

In the embodiment of the present disclosure, the network identity of the PLMN can include network codes. For example, the network codes of China Mobile include: 46000, 46002, 46007, and 46008. The network codes of China Unicom include: 46001, 46006 and 46009.

Specifically, when the mobile communication terminal determines the network standard that can be supported by it, the network identity of the PLMN in compliance with the network standard can be added into the EPLMN list. For example, when the mobile communication terminal only supports a mobile user identification card, network identities that stand for mobility can be added into the EPLMN list.

S103: A communication connection between the mobile communication terminal and a matching PLMN is established if the matching PLMN is found to match a network identity in the EPLMN list.

In the embodiment of the present disclosure, the mobile communication terminal scans and extracts the network identity of the PLMN broadcasted by the base station. The mobile communication terminal compares the network identity of the PLMN scanned and extracted with the network identities of the PLMNs in the EPLMN list for a match. If there is a match, a communication connection between the mobile communication terminal and the matching PLMN will be established.

As shown in FIG. 1, the embodiment of the present disclosure determines the standard supported by the mobile communication terminal, and adds the network identity of the determined standard PLMN supported by the mobile communication terminal into the EPLMN list. When a PLMN is found to match a network identity in the EPLMN list, a communication connection between the mobile communication terminal and the matching PLMN is established. The embodiment of the present disclosure adds the network identity of the determined standard PLMN supported by the mobile communication terminal into the EPLMN list. The EPLMN list stores network identities of PLMNs that are regarded as equivalent to a certain extent by the mobile communication terminal. Therefore, when the mobile communication terminal connects to a network based on the EPLMN list, which has stored network identities of standard PLMNs supported by the mobile communication terminal, the mobile communication terminal searches networks based on the current location when the mobile communication terminal is inserted with a user identification card for the first time. Thus it significantly heightens the chance of finding a PLMN whose network identity matches a network identity that is already stored in the EPLMN list during the process of network searching, as well as the possibility of the mobile communication terminal accessing to a network at the current location. It is instrumental in minimizing the waiting time when users are communicating (ideally, it only takes a few seconds for the mobile communication terminal to complete network connection), and thus is instrumental in greatly improving users' communication experience.

Please refer to FIG. 2. FIG. 2 is a flow chart of the method for accessing to a network according to another embodiment of the present disclosure. The method for accessing to a network includes following blocks:

In the embodiment of the present disclosure, network standards refer to the types of the networks. Types of network standards commonly seen in China are code division multiple access (CDMA), with mobile phones using CDMA 1× at frequency band 800 MHz; global system for mobile communication (GSM), with mobile phones using frequency bands 900/1800/1900 MHZ; GSM 1× dual-mode (i.e. wideband CDMA, WCDMA) in the recent years, taking frequency bands 900/1800 HMZ; 3G mobile communication technology, taking frequency bands 900/1800/1900/2100 HMZ; and 4G technology, taking frequency bands 1920-2170 MHZ.

In the embodiment of the present disclosure, the network standards that can be supported by each mobile communication terminal are limited and definite. That is, after a mobile communication terminal is produced, the network standards supported by the mobile communication terminal are determined.

S202: The types of user identification cards supported by the mobile communication terminal are determined based on the network standard supported by the mobile communication terminal.

In the embodiment of the present disclosure, the user identification card can be a subscriber identity module (SIM) card. When the network standard that can be supported by the mobile communication terminal is determined, the type of user identification card that can be supported by the mobile communication terminal is determined.

S203: The network identity of the PLMN in compliance with the network standard supported by the mobile communication terminal is determined based on the type of user identification card supported by the mobile communication card.

In the embodiment of the present disclosure, Public Land Mobile Network (PLMN) is a network built and operated by the government or operators approved by the government for the purpose of providing land-bound mobile communication services to the public.

In the embodiment of the present disclosure, the network identity of the PLMN can include network codes. For example, the network codes of China Mobile include: 46000, 46002, 46007, and 46008. The network codes of China Unicorn include: 46001, 46006 and 46009.

S204: The network identity is added into the equivalent public land mobile network (EPLMN) list.

In the embodiment of the present disclosure, an EPLMN is a PLMN that has the same status and level of priority as the PLMN currently chosen by the user's terminal. The EPLMN mainly solves problems related to user retention and roaming strategy in shared networks and original networks. Operators can deploy equivalent PLMNs so to realize sharing of communication network resources. From a business perspective, the practice realizes sharing of communication network resources among different PLMNs defined by the same operator or PLMNs of different operators.

Specifically, when the mobile communication terminal determines the network standard that can be supported by it, the network identity of the PLMN in compliance with the network standard can be added into the EPLMN list. For example, when the mobile communication terminal only supports a mobile user identification card, network identities that stand for mobility can be added into the EPLMN list.

S205: A communication connection between the mobile communication terminal and a matching PLMN is established if the matching PLMN is found to match a network identity in the EPLMN list.

In the embodiment of the present disclosure, the mobile communication terminal scans and extracts the network identity of the PLMN broadcasted by the base station. The mobile communication terminal compares the network identity of the PLMN scanned and extracted with the network identities of the PLMNs in the EPLMN list for a match. If there is a match, a communication connection between the mobile communication terminal and the matching PLMN will be established.

In the embodiment of the present disclosure, operators broadcast the network identities of their own PLMNs, so that each mobile communication terminals can scan and extract these network identities.

S206: A reminder message is outputted to remind the user of the time needed to connect to the network this time.

As an optional method of implementation, if the mobile communication terminal detects a match between the network identity of the PLMN scanned and extracted and the network identities of PLMNs in the EPLMN list, it implies that the search of network is successful. Then, a request for connection can be sent to the network so to establish a connection. For users or testers to better understand the details of the connection to the network this time, a reminder message can be outputted to remind the user of the time needed to connect to the network this time.

As another optional method of implementation, if there is no match between the network identity of the PLMN scanned and extracted and the network identities of PLMNs in the EPLMN list, it implies that accessing to the network fails this time. The mobile communication terminal can detect reasons of the failure and remind users how to update the EPLMN list.

FIG. 2 illustrates in detail how the mobile communication terminal determines the network identity of the PLMN in compliance with the network standard supported by the mobile communication terminal based on the type of user identification card, adds the network identity into the EPLMN list, and connects to the network based on the EPLMN list. It reminds the user of the time needed to connect to the network when the connection succeeds, and reminds the user of the reasons of failure when the connection fails. The embodiment of the present disclosure not only reduces the time needed to connect to the network in advance, but also sends a reminder message when accessing to the network is completed. It can elevate user experience as well.

Please refer to FIG. 3. FIG. 3 is a block diagram of a mobile communication terminal according to a first embodiment of the present disclosure. As shown in FIG. 3, the mobile communication terminal can include a standard determining unit 301, an adding unit 302, and an accessing unit 303.

The standard determining unit 301 is used to determine the network standards supported by the mobile communication terminal.

In the embodiment of the present disclosure, network standards refer to the types of the networks. Types of network standards commonly seen in China are code division multiple access (CDMA), with mobile phones using CDMA 1× at frequency band 800 MHz; global system for mobile communication (GSM), with mobile phones using frequency bands 900/1800/1900 MHZ; GSM 1× dual-mode (i.e. wideband CDMA, WCDMA) in the recent years, taking frequency bands 900/1800 HMZ; 3G mobile communication technology, taking frequency bands 900/1800/1900/2100 HMZ; and 4G technology, taking frequency bands 1920-2170 MHZ.

In the embodiment of the present disclosure, the network standards that can be supported by each mobile communication terminal are limited and definite. That is, after a mobile communication terminal is produced, the network standards supported by the mobile communication terminal are determined.

The adding unit 302 is used to add network identities of the PLMN in compliance with the network standards supported by the mobile communication terminal determined by the standard determining unit 301 into the EPLMN list.

In the embodiment of the present disclosure, Public Land Mobile Network (PLMN) is a network built and operated by the government or operators approved by the government for the purpose of providing land-bound mobile communication services to the public. The network is usually connected to PSTN, forming a communication network that covers a whole region or country. For example, the network identity of PLMN of China Mobile is 46000, and the network identity of China Unicom is 46001. PLMN is a wireless communication system, inclined to be accessed by land-bound users riding on transportation tools or moving on foot. Such a system can be independent, but it is usually connected to a landline telephone system, such as PSTN. However, there are also more and more mobile and portable Internet users. An ideal PLMN system provides services to mobile and portable users equivalent to that provides to landline users. It can be especially challenging in areas with complicated terrains, because it is difficult to find and maintain a base station. There are also many obstacles in an urban environment, such as noises and interfering radiation that can be evoked by buildings and radio frequencies.

In the embodiment of the present disclosure, an EPLMN is a PLMN that has the same status and level of priority as the PLMN currently chosen by the user's terminal. The EPLMN mainly solves problems related to user retention and roaming strategy in shared networks and original networks. Operators can deploy equivalent PLMNs so to realize sharing of communication network resources. From a business perspective, the practice realizes sharing of communication network resources among different PLMNs defined by the same operator or PLMNs of different operators.

In the embodiment of the present disclosure, the network identity of the PLMN can include network codes. For example, the network codes of China Mobile include: 46000, 46002, 46007, and 46008. The network codes of China Unicorn include: 46001, 46006 and 46009.

Specifically, when the standard determining unit 301 determines the network standard that can be supported by it, the network identity of the PLMN in compliance with the network standard can be added into the EPLMN list. For example, when the mobile communication terminal only supports a mobile user identification card, network identities that stand for mobility can be added into the EPLMN list.

The accessing unit 303 is used to establish a communication connection between the mobile communication terminal and a matching PLMN if the matching PLMN is found to match a network identity in the EPLMN list.

The accessing unit 303 is used to scan and extract the network identities of PLMN broadcasted by base stations. The accessing unit 303 is also used to compare the network identities of the PLMNs scanned and extracted with the network identities of the PLMNs in the EPLMN list for a match. The accessing unit 303 is further used to establish a communication connection between the mobile communication terminal and the matching PLMN.

As shown in FIG. 3, the standard determining unit 301 determines the standard supported by the mobile communication terminal. The adding unit 302 adds the network identity of the determined standard PLMN supported by the mobile communication terminal into the EPLMN list. When a PLMN is found to match a network identity in the EPLMN list, the accessing unit 303 establishes a communication connection between the mobile communication terminal and the matching PLMN. The accessing unit 302 adds the network identity of the determined standard PLMN supported by the mobile communication terminal into the EPLMN list. The EPLMN list stores network identities of PLMNs that are regarded as equivalent to a certain extent by the mobile communication terminal. Therefore, when the mobile communication terminal connects to a network based on the EPLMN list, which has stored network identities of standard PLMNs supported by the mobile communication terminal, it searches networks based on the current location when it is inserted with a user identification card for the first time. Thus it significantly heightens the chance of finding a PLMN whose network identity matches a network identity that is already stored in the EPLMN list during the process of network searching, as well as the possibility of the mobile communication terminal accessing to a network at the current location. It is instrumental in minimizing the waiting time when users are communicating (ideally, it only takes a few seconds for the mobile communication terminal to complete network connection), and thus is instrumental in greatly improving users' communication experience.
